CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 272,490, dated February20, 1883.

Application filed March 9, 1882. (No model.)

To all whom it may concern Be it known that I, GEORGE F. SKANK, a

cultivators, iirst,in the gangs, being especially adapted to thecultivation of listed corn, be-` ing so arranged that they can bechanged at the will of the operator in regard to depth and distanceapart by simply drawing a pin in the casting on the end of the beam, andraising or lowering them to regulate the depth and putting them closertogether or farther apart, as may be desired. Each gang or beam A hasthree standards, B B B, and Vthree shovels, a a a, so arranged by holesb in the posts that theymay be raised or lowered to snit the rows ofcorn, and the shovels smaller than those in ordinary use, the ,objectbeing to prevent the covering ofthe corn while small, listed corn beingplanted in deep furrows.

In the drawings, Figure l is a top view,

lshowing the shape of coupling, thel castings or slides W, which holdthe evener G, and slotted brace O', which prevents the slides frompulling sidewise,the draft-chains F, runmoved forward or backward toassist in adjusting the weight ot' the tongue. The evener is swung inthe castings on the topof the tongue, and works nearly perpendicularly,and the chains run from the ends of the evene'r O, under pulleysheretofore described, and are 'attached to the whifdetrees for thepurpose of preventing side draft and to com pel each horse t0 do hisshare of the work.

The couplings I are made of cast-iron, and work upon the axle R, andhave a deep groove toM receive one of the earsof the clevis I', which'is attached to the end of the beam A. SThese ears are ot' the samethickness as the" groove in the couplings I, and their object is topermit the raising or lowering ofthe beam A as one orother of the earsis placed in the groove. The' ends of the ears are, rounded, so that thegangs can have a lateral movement.` e Thus a rm knuckleis made androcking is prevented, while thev beams are easily moved, eitherlaterally or vertically. The object of the ears is to lower or raise thebeams and gangs of plows to regulate the depth of plowing. The clevis Ihas three holes in its rear end to receive a pin passing through thefront end of the beam, for the purpose of increasing the distance fromthe frame, and the coupling I also has three openings, t', (only ningfrom ends ot' evener O (which works up one shown,) to permit the gangsto approach and down) and passing under pulleys G, which are fastened tothe front part ot' the frame. Fig. 2 is a side view, showing shape offrame couplings, and gangs.` Y

The frame H of this cultivator is made'of solid wrought-iron, withdouble arch turned in square corners and welded together at the bottom,and turned out to form theaxle, on which is placed the coupling-castingsl, sandcap K, and wheel L. arch is to have a draft-pulley far enough infront of the axle to take the-draft oft' the necks of the horses.

To the outsides of the front arch is bolted an iron, M, extending downeven with the axle, then turning a square corner out, and connectingwith an ironstrap which extends forward from the sand-cap K, immediatelyoutside of the coupling-casting I. Upon the front iron are boltedpulleys G, under which the draft-chains run.

The tongue T is bolted on top of the arches H M, and upon top of thetongue are placed castings W, to hold the evener C, so as to be orrecede from each other. The beam is made of wood or iron, having amortise or opening to admit the middle one ot the three standards. Thestandards are of wrought-iron, and are made adjustable by means ot'holes b in the braces, to raise or lower them, according t0 the depth ofthe furrow inwhich the corn is planted, the inside standard being thelongest. The braces are adjustable by means ot' The object of the squarethe holes b. The shovels are small and twisted,

and fastened to the standards by means ot' bolts. i

Having thus described my invention,what I claim, and desire to secure byLetters Patent, 1s-

In acultivator, the combination ofthe adjustable evener O, pivotedbetween the adjustable slotted castings W, slotted brace C', arch orframe H, chains F, and pulleys G, all constructed as herein shown anddescribed.
